1 Claim.

This invention relates to an improvement in woven, knitted, braided, or otherwise fabricated tapes, and particularly to tapes having corded edges for mounting slide fasteners or the like.

So-called slide fasteners, employed for fastening articles of wearing apparel, such for instance, as jackets, coats, sweaters, etc., are usually mounted upon tapes, and such tapes, after the mounting of the slide fasteners, have been sewn or otherwise secured to the abutting edges of a garment. Ordinarily, tapes, though initially straight,smcoth and flat, become distorted and wrinkled by the application of the slide fasteners thereto and hence impart an unsightly appearance to the garment or other article to which such tapes may be applied.

'I'he distortion of tapes resulting from the application of the fasteners to one edge thereof, as above described, will often eiect the curving of the tape in a direction away from the edge upon which the said fasteners are applied, and when sewn to the normally-straight edge of a garment, the tape will reassert itself, to some appreciable degree at least, and not only again distort itself but correspondingly distort and wrinkle the edge of the garment to which it is secured.

It is the main object of the present invention to provide a superior so-called corded-edge tape which will not objectionably distort when slide 30 fasteners or the like are attached to its edge.

A further object is to provide a corded-edge tape equipped with slide fasteners which will be relatively freefrom wrinkles, puckers, and the like, and thus adapt itself for uniform application to a garment.

With the above and other objects in view, as will appear to those skilled in the art from the following, considered in conjunction with the accompanying drawing and appended claim, the 40 present invention includes all features disclosed therein which are novel over the prior art.

In the accompanying drawing: Fig. 1 is a broken face view of a concavoconvex corded-edge tape embodying the present invention;

Fig. 2 is a transverse sectional view thereof taken on the line 2-2 of Fig. 1;

Fig. 3 is a face view of the tape after the application thereto of the series of spaced clip-like 50 slide fasteners;

Fig. 4 is a transverse sectional view taken on the line 5 4 of Fig. 3; and n v Fig. 5 is a broken longitudinal sectional view taken on the line 5-5 of Fig. 3. 55 The tape lo illustrated in the accompanying drawing consists of a relatively-thin and flexible body or flap II substantially plain along one edge I2 and built up in any approved manner familiar to those skilled in the art to provide a thickened, corded or beaded edge I3 having, for

instance, a longitudinally-extending group of strands I4 incorporated therein.

It will be noted by comparison of Figs. 1 and 3 that in Fig. l the tape is curved in such manner that its thickened or corded edge I3 constitutes the concave inner or shorter edge of the curved tape, while its relatively-plain opposite edge I2 constitutes the convex outer and longer boundary of the curved tape.

'Ihe curved corded-edge tape having the characteristics above referred to may be produced in a variety of ways, such, for instance, as by weaving the corded edge I3 shorter than the opposite edge I2 of the tape.

The desired concave-convex curved effect` may be obtained by forming the corded edge I3 of the tape of strands which are relatively elastic as compared to the strands of the body or ap Il and particularly those of the edge I2.. For instance, ordinary cotton warp strands may be employed for the production of the body or4` flap Il, while the corded edge I3 may 'have incorporated therein hard-twisted yarn. Inasmuch as during the weaving operation tension is applied to all of the warps or other longitudinal strands, the hard-twisted yarns will be stretched to a relatively-greater degree than the ordinary strands, and after the weaving is completed and the tape released from restraint, the relativelyelastic hard-twisted strands in the corded edge I3 will contract and thus impart the desired curvature to the tape.

Other methods of manufacture are also available, such, for instance, as incorporating in thecorded edge I3 strands which have a greater co- `emcient of shrinkage when wetted or dyed than have the strands in the body or `flap-portion II. Thus, after weaving, the dyeing or other appropriate wetting of the tape will effect a contraction of the strands in the corded edge I3" to a* greater degree than in the body or flap Il, and

thus impart the desired curvature to the tape.

Under this method for the purpose just described, various diiferentially-shrinkable materials are available, such, for instance, as wool vs. cotton, mercerized cotton vs. unmercerized cotton, etc.

Another mode of manufacture which is Worthy of mention consists in weaving in more weft picks adjacent the plain edge I2 than are woven into the fabric at or adjacent the corded edge
